Anyone else here shooting the X mount version of the Thypoch 28 1.4 and have issues with it not focusing to infinity unless you stop down to ~f/4-5.6? Mine is acting that way and unfortunately no way to return for a different copy and Thypoch was of no help; they just referred me to third party repair shops where I was quoted $175+ to shim and adjust focus.
The lens is a blast to shoot otherwise, and I don't need to shoot infinity at 1.4 that often, but would be nice if I could. I don't know exactly how far it will focus wide open, but it's not too far.
So far it seems that even backing off doesn't do the trick. I'll give it another go, but I tried taking multiple photos pulling focus in slightly each time. If I stop down to 5.6 or more, hard stopped over on the focus ring, infinity is in focus, it appears to me.
I'll still give that a try again though regardless in a more controlled way.
I just punched in as far as I could, and turned focus peaking off, and definitely can confirm that it won’t focus to infinity, even if I back off. If I back off from infinity, the focus gets worse. It seems that approximately 15 to 20 feet away is as far away as it will focus at f/1.4

All reviews say that the lens focuses beyond infinity. To focus at infinity, you need to turn the ring about 1 mm.
Register is wrong. 'Backing off' or shimming will make it worse. Lens does nor get close enough to tge sensor.
Ideally return to where you purchased it. If not pay out f9r adjustment, if that is possible.
Interesting. Not close enough to the sensor. That’s not “fixable” is it? I bought it open box/used online and didn’t notice until it was past the return period to that’s not possible unfortunately

Only a repair man can tell you whether adjustmentis possible and he'll probably have to strip it down to find out.
Man, it’s really unfortunate Thypoch doesn’t want to take ownership of it when it seems like it’s 100% a manufacturing defect and not something that happened to the lens after the fact

Unfortunately the original purchase wasn’t on my credit card. Annndddd I got it off eBay from someone 🙃 that’s what I get for trying to save a few bucks (and for wanting a lens that’s very difficult to find on the used market).

To be fair to them, nobody knows of it's been got at already to create the problem.

Also a very fair take. Thankfully, it sounds like after a few months of back and forth, they're going to "fix" it for me. They acknowledged that the behavior it's exhibiting is sort of a defect and needs shimming to fix the flange distance.

I repeat, shimming will only help if it focused 'beyond' infinity, the lens is too close to the sensor. I have shimmed quite a few cheap dumb adaptors as they almost always are too thin
If your lens doesn't reach infinity when at the he hard stop it is not getting close enough to the sensor, and needs adjustment of the lens units in the focussing mount.
Semantics, PhotoTech will get it sorted out, that’s not for me to worry about, I’m not the one doing anything to the lens. Just going off Thypoch telling me “this is typically corrected by adjusting the shims at the lens mount”

'Shimming' usually implies adding shims. Ad justing the shims I this caseprobably removing them, the opposite, semantics?
Just got the word form Thypoch that they sent the repair shop the parts to fix the lens! Who knows what "parts" were needed, but at this point I'm just happy the focus will be good to go
Honestly the Zf is what I wanted the Thypoch on, the 28 and 35 render exactly how I want a lens to render. Borderline medium format focus falloff style rendering, like the Mitakon 65 on GFX. The 28 isn’t as pronounced on Fuji, but it’s still there and I love it!

Thats great to hear. I'm loving the Typoch on Nikon Z. It would be fun to use it on a Fuji XE body.
